CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 250,C33, dated November22, 1881,

Application filed June 17, [881.

T a all whom it may concern:

Beit known that l, W. E.YOUNG, of the city of Chicago, county of Cook,and State of Illinois, have invented certain Improvements inCar-Starters, of which the following is a specification.

The object of my invention is to provide a street-car with devices andcombinations of devices by means of which the driver may exert apart orall of the force necessary to start the car, and do this quickly andeasily. I have accomplished this object by means of the parts anddevices hereinafter described, with reference to the accompanyingdrawings, in Which- Figure 1 represents an inner face view of one of thecarrying-wheels, a longitudinal section of a part of the floor, and across-section of one axle of a street-car, together with an elevation ofthe cap D, its shells, a shaft, S, and other parts; Fig. 2, an edge viewof cap D,aninnerview ofcap 0, and other parts; Fig.3, a section of Fig.2, taken as indicated by the broken line 3 3 in Fig. 2; Fig. 4, a backview of the cap 0; Fig. 5, a horizontal central section of toothed diskE, cap D, cap 0, and other parts; Fig. 6, a detail view of the hanger G;Fig. 7, a perspective of one edge of cap D and one ofits protuberances,g, the pin for the hanger, and other parts.

The toothed disk E may he made of any suitable size and thickness, andmayhave a plain face or a dished face to correspond with the face of thecarrying-wheel. It is provided on its inner face and upon the outer edgeofsame with bevel-gear to correspond with the form of bevelpinion E,which is designed to operate upon it. It is also provided with aprojecting hub, e,fitting arouudthe axle C. The shell of frame D is alsocircular in form, covers and incloses the inner face of the disk, so asto exclude mud and slush and make room for certain parts within it, andis provided with a hub, 6 like that of the disk, but larger and shorter,so as to slip over hub e and be held in place by collar 0 which is heldin position by set-screw s which holds it and hub a fast upon the axleC. The shell or frame D is provided with flanged edges extending overbeyond the outer face of the disk, so as to exclude dirt and slush fromthe (No model.)

bevel-gear iuclosed, the bevel-pinion E, and other parts. The shell isalso provided with an upright arm, t, that passes up through the floor Aand serves to hold it stationary, and it also serves as a fulcrum to thegeared leverage, by meansofwhichthecarisstarted. Atbothends of itshorizontal diameter the shell D is enlarged at d and cl, for the purposeof inclosing the operating devices and excluding dirt. The flanged rimis cutoff atright angles with its diameter-across theenlargementsdandd,leaving flat edge surfaces, from the upper portion ofwhich project pins g. The pin 9 in each enlargement supports a swinginghanger, G, the upper hole. g, in which is made oblong, as shown in Fig.6, in order that the hanger may have some play-room lengthwise when uponthe ping. The lower end of the hanger is provided with a round hole,through which the shaft S is passed, and upon which pinion E is placedand held by a spline against turning thereon, as shown in Fig.2,so thatthe shaft may have someplay lengthwise in the pinion. Atoothed pawl, It,is pivoted in a depression made for it in thelower portion of theenlargement (Z back of and beneath the pinion E. Capcis bolted to andcompletely covers the openingof the enlargement. It has a curved slot,f, through which passes and swings the shaft S. One portion of the rimof this cap 0 projects back of the disk E, to serve as a stay to preventthe shell and disk from spreading asunder when the gears are operated.

The shield 0, pivoted to cap 0, as shown in Fig. 3, fits closely aroundthe shaft S, and serves to cover the unfilled portion of slot f andexclude dust and dirt. The shaft Sextends out from the shell or frame D,forward immediately under the brake-staff, where it is supported by asuitable bearing depending from the floor or platform. To its outer endis securely fastened the bevel-gear P. The lower end of the brake-staffturns in a suitable socket provided for it in the bearing, as shown.

The bevel-gear P is held to the staff B against turning by the spline K,but has ver tical play, in order thatitmay be readily moved into and outof gear with pinion P. Itis held up out of gear with it by spiral springQ, and

depressed into gear with it by rod T, whichis attached to it and extendsup through floor, and is operated by the foot of the driver. The upperportion or hub of this gear P is provided with teeth, so as to form partof a clutch. On the brake-staff B, between this gear and the floor, is asleeve, J, to the upper end of which is fastened the brake-chain, whilethe lower end is toothed to correspond with the hub or pinion P, andform with it a clutch. The lower end of the sleeve is enlarged, so thatits outer edge is provided with the teeth for clutching, while the inneredge is plain next the statt', and forms a ring or shoulder, which restson the upper end of the spline K, and thus the sleeve is held up inplace and allowed to turn freely and independently when the gear isdepressed.

The operation ot'the hereinbefore-described parts and devices may bedescribed as follows: The spring Q naturally holds the gear I? up inconnection with the sleeve J, so that when the brake-handle is turnedthe chain is wound up and the brake applied. The brake may be releasedeither by allowing the brake-handle to turn around in the reversedirection or by depressing the gear P by means of the rod T. \Vhen thegear P is depressed into connection with gear P and the brake-handleturned ahead the pinion E, revolving with the shaft S in the directionindicated by the arrow in Fig. 2, engages with the toothed pawl B,which, turning on its pivot, throws the pinion in the di rection of thedisk E, and when the pinion reaches and meshes with the gear of the disk(the brake-handle still continuing in motion) its tendency is to runaround up that gear, which it does do, thereby freeing the pawl It,which then drops back into its former position. The pinion runs up thegear until the shoulder a on thehangerG meets a corresponding shoulder,n, on the cap 0, which stops the swing of the hanger G. Now, ifsuflicient force is exerted upon the brake-handle, the disk E must turn,and with it the axle G and wheel B, and thus will be accomplished theobject of my invention.

The larger the toothed disk may be theless the power required to turnthe axle and start the car.

In the foregoing specification I have confined the description to theoperative parts, and have shown but one wheel and one axle in thedrawings.

The devices in enlargement d are a duplication of those in enlargementd, and may be used when the car is to be run with the other endforemost.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the shaft B, having the spline K seated therein,as described, and the loose sleeve J, having its lower end so enlargedthat its outer edge provided with teeth T will form a shoulder withinthe circle ofsuch teeth to rest upon the top end of the spline, thewhole adapted to hold the sleeve up out of the way whenever the saidshaft may be used to operate the starting devices, substantially asdescribed.

2. The combination of bevel-gear P on shaft S with bevel-gear I onthelower endot' shaft B, spring Q, and foot-lever T, adapted to throwsaid bevel-gears into mesh and out of mesh with each other, in order toeither revolve shaft S or to brake the motion of the car at the will ofthe operator, substantially as described.

3. The combination of the bevel-gear P, shaft S, pinion E, pawl It, andhanger Gr,substantially as and for the purpose described.

4. The combination of the hanger G and the cap 0, constructedsubstantially as and for the purpose described.

5. The oornbination of pawl R with pinion E, hanger G, cap a, and thegeared disk E, substantially as and for the purpose described.

6. The (JOll'lblllZltlOIl of shell .D, having the enlargements d and d,with the geared disk E, substantially as and for the purpose described.
